Working in your pajamas pales in comparison to having a higher seniority number!! I'm not sure that the new-hire 767 guys would agree with your view of the world from the mighty 747...seniority is everything. Wouldn't you agree?

I also see that it may not be a fair way to pick and choose the 767-qualified guys over those that are in the pool already, but the company is in a position (and has the need) to do it this way.
